mod_cloud_notify_encrypted: Ensure body substring remains valid UTF-8
The `body:sub()` call risks splitting the string in the middle of a
multi-byte UTF-8 sequence. This should have been caught by util.stanza
validation, but that would have caused some havoc, at the very least causing
the notification to not be sent.
There have been no reports of this happening. Likely because this module
isn't widely deployed among users with languages that use many longer UTF-8
sequences.
The util.encodings.utf8.valid() function is O(n) where only the last
sequence really needs to be checked, but it's in C and expected to be fast.

--- labels: - 'Stage-Alpha' summary: Restrict MUC configuration options to server admins ... Introduction ============ Sometimes, especially on public services, you may want to allow people to create their own rooms, but prevent some options from being modified by normal users. For example, using this module you can prevent users from making rooms persistent, or making rooms publicly visible. Details ======= You need to supply a list of options that will be restricted to admins. Available options can vary, but the following table lists Prosody's built-in options (as defined in XEP-0045): Name Description --------------------------------- ------------------------------------------- muc\#roomconfig\_roomname The title/name of the room muc\#roomconfig\_roomdesc The description of the room muc\#roomconfig\_persistentroom Whether the room should remain when empty muc\#roomconfig\_publicroom Whether the room is publicly visible muc\#roomconfig\_changesubject Whether occupants can change the subject muc\#roomconfig\_whois Control who can see occupant's real JIDs muc\#roomconfig\_roomsecret The room password muc\#roomconfig\_moderatedroom Whether the room is moderated muc\#roomconfig\_membersonly Whether the room is members-only muc\#roomconfig\_historylength The length of the room history Some plugins may add other options to the room config (in Prosody 0.10+), for which you will need to consult their documentation for the full option name. Configuration ============= Enable the plugin on a MUC host (do not put it in your global modules\_enabled list): ``` {.lua} Component "conference.example.com" "muc" modules_enabled = { "muc_config_restrict" } muc_config_restricted = { "muc#roomconfig_persistentroom"; -- Prevent non-admins from changing a room's persistence setting "muc#roomconfig_membersonly"; -- Prevent non-admins from changing whether rooms are members-only } ``` Compatibility ============= ------- -------------- trunk Works 0.9 Doesn't work 0.8 Doesn't work ------- --------------
